A display device comprising:
- a plurality of light emitting elements which emit light when supplied with a driving current, each light emitting element including an organic light emitting layer which emits white light;
- a plurality of driving transistors which supply the driving current to the light emitting elements;
- a plurality of photo sensing parts which sense light amounts according to emission of the light from the light emitting elements and output sense signals according to the sensed light amounts;
- and
- a plurality of color filters which are disposed on the plurality of driving transistors and the plurality of photo sensing parts,
- wherein each of the color filters overlaps each of the photo sensing parts and the color filter is disposed between the light emitting elements and the photo sensing parts.
